Three general approaches are available for the analysis of supersonic ejector performance. In order of complexity, they are 1 one-dimensional flow models, 2 combined one- and two-dimensional interactive flow models with a superimposed viscous mixing component, and 3 application of finite-difference approximation of the Navier-Stokes equations to the overall flowfield within the ejector. The objectives of this presentation will be to provide a brief overview of each of the methods for predicting supersonic ejector performance, to outline the significant features and advantagesdisadvantages of each method, and to suggest possible future directions for consideration.
